BEREA, Ohio — Full pads were in use for the first time on Saturday and fans were treated to plenty of contact, especially during the “anything goes” siren period.

The first big hit of the day was delivered by first-year linebacker James Burgess on rookie running back Matthew Dayes, who was stopped cold for no gain in a pad-crunching collision.

Dayes also caught a short pass from DeShone Kizer and was promptly drilled by Jamie Collins.

Welcome to the NFL, rookie!
